Your checking 2 months later. Definitely the pics have been taken down. Its served its purpose of being "useless" since it wasnt ever analyzed but for a few sparse people who helped.

I dont know what tickled you but you can keep your personal comments about what you feel regarding my attitude to yourself.

So you came to an age old post to tell me i wont receive any replies ? Whats wrong with you.

If you have an attitude to judge other people here, i think i can be aggressive with my posts. Nothing wrong in that.

Ofcourse i was in a hurry, with an 'expensive' faulty lens, and just a day or 2 to return it. And because i couldnt get a picture comparision, i now have the faulty lens, thanks to members like you, who wanna play shrink instead of help with the actual subject at hand. And its pretty daft you came 3 months later expecting the link to work and offer free counselling.

But theres no sigma service in my area. Its done by other people ill trained. They dont actually have a service center here. They just have a tie up with some small workshops. Firstly the seller never gives the actual address of the service center tel numbers or address (proving its some shoddy fly-by-night repair guy whom theyve cajoled to 'act' as a service centre) and he asks to hand it over to him and that he will mail it to that guy who will in turn meddle with it and send it back.

Further i lost faith when i called a canon service centre, another fly-by-night tie up, the guy there said.... "what lens, a canon lens", then is asking someone in his place "we repair canon ???", for a long time they were unsure if they do canon, then a crude worker guywho cant speak any english comes to the line and says "oh its a canon lens ?, actually we do canon lenses, we have done a few too !!, but they are very difficult to repair sir, send it in and ill ~see~ what i can do. Else ill send it to xxxxx city and ask them to do it because im not sure"

So i wanted to issue them a consumer court notice and guess what, theres only 1 guy with a cellphone who claims hes the sales manager. When i asked where his office is, he refused to inform me, said he has no office but works from home. Where will i even send the court notice for deficiency in services ?? That too in a metro city like mine. The head office i believe is in another city 2000 miles away, my court doesnt even have jurisdiction there, cant summon him from another city. Id drather suffer with the lens. They play on these points, outright deprivation of your consumer rights, knowing that you cant fight them because they are unreachable. As long as your lens works ok then all is fine.

Im a person who keeps my gear in showroom condition. Literally. For example, My 3 year old lens which ive used quite regularly will look like it was taken of the showroom shelf, not even handling or hairline scratches. I cant bear to see these guys mail it, damage it, scratch it and give it in worse condition. In my country ive experienced this all too often and several of my brand new products (phones, laptops) taken in for service and given back with several additional scratches repair marks.

I have the canon 500d and 550d bodies. I dont think they have micro adjust. But im able to get by with some shots. Its very tought to maually focus with a UWA. You can hardly tell through the viewfinder as to whats in focus and whats not.

The only way is to use the zoomed focus checking on the lcd and go from there i guess ?

Most of the time, having it set to infinity will get you a good shot. Once I put it on manual focus, then forgot it was on manual focus and still took reasonable pictures. Unless you are getting close most of the time you will be using it at near infinity.

But I do not know your shooting style. I just gave you mine.
So for you, why not take several pictures, the same picture with various focal distance settings, and then see how it performs?

You can also find a test online that will determine if your lens front focuses or back focuses. If that is the case, then let it autofocus, then manually adjust it just a bit and you should be able to get a decent picture.
